Be it knbwnthat I, THOMAS E. DEMPSE-Y', a, zici'zen of the United States, residing at New York, in the. county of New York and State of New York have invented new aiicl useful Improvements in v vulcanizi g De: vices, of which the following is e Specificati0n.. x I" This invention relates to'improvements in portablevulqai izers 1. th'iit class croiiiprising a cup br' recept cl'effQi retaining-Ea fluent fuel, which when ignited, serves t'o heat the receptacle i i a manner-to-rulcim ize the material thereheneath.
